Pipelines

We have designed some of the most challenging pipeline systems in the world using state-of-the-art solutions and technical engineering tools, adopted to provide cost-effective and robust solutions for our clients.

Lars Eriksen

Ramboll has more than three decades of experience with offshore infrastructure. We cover transmission pipelines as well as infield flow line systems, from concept to design. For maturing pipelines, we handle all aspects of brownfield-engineering related to the reassessment of structural integrity.

We design complex High Pressure/High Temperature (HPHT) flow lines, and we specialise in subsea tie-back projects with topographical challenges, combined with HPHT operation.

Multidisciplinary expertise

As a multidisciplinary international engineering and design company, we always set the best team for a given project and we can offer services for all phases of a project’s life cycle, from financial studies and impact assessments to construction management, fitness for reassessments and lifetime extensions.

Subsea design competencies

Our proven pipeline engineering competencies are based on an advanced understanding of critical issues such as structural behaviour and hydrodynamics under adverse conditions. We offer offshore expertise in route selection, geophysical and geotechnical route surveying, system optimisation, laying and trenching analysis, riser systems, flow assurance, subsea components and installation.

Pipeline reassessments for maturing fields

Ramboll supports clients in increasing efficiency and prolonging production on mature fields. Our in-depth knowledge extends to offshore plat-forms and FPSOs, which gives us the required overview and experience to handle tie-back or tie-in projects for all relevant interfaces between pipeline, subsea completion and platform or FPSO.

Connecting to onshore infrastructure

Because of our multidisciplinary profile, Ramboll can also assist in connecting subsea highways with onshore infrastructure, by engaging our civil engineering experts, who are specialists within areas such as ports & marine, roads, construction and contract management.

The Gina Krog field is situated roughly 30 km northwest of the Sleipner field and 230 km southwest of Sta-vanger, Norway. It is estimated to hold 225 million barrels of oil and gas.

Ramboll has won a large contract worth a double-digit million euro figure for Polish GAZ-SYSTEM for the environmental assessment and design of the offshore Baltic Pipe between Denmark and Poland. The pipeline will connect gas in the North Sea with consumers in Central and Eastern Europe and thereby strengthen the security of supply.
